• Working around Django's ORM to do interesting things with GFKs May 03, 2012 00:05

  In this post I want to discuss how to work around some of the shortcomings of djangos ORM when dealing with Generic Foreign Keys (GFKs).

  At the end of the post I'll show how to work around django's lack of correctly CAST-ing when the generic foreign key is of a different column type than the objects it may point to.

• Micawber, a python library for extracting rich content from URLs April 19, 2012 11:13

  A while ago I wrote about an awesome API for retrieving metadata about URLs called oembed. I'm writing to announce a new project I've been working on called micawber, which is very similar but with a cleaner API and not restricted to django projects.

• Using Redis Pub/Sub and IRC for Error Logging with Python April 15, 2012 11:23

  I recently rewrote my personal site using flask and peewee, breaking a good amount of stuff in the process. I was trying to track down the errors by tailing log files, but that didn't help alert me to new errors that someone visiting the site might stir up. I thought about setting up error emails a-la django, which is a tried and true method...but then I happened on a different approach. I won't say it's the most elegant solution, but it was a quick hack and the results have been awesome. I wrote a custom logging handler that pushes JSON-encoded log record data to a redis pub/sub channel. I then have an IRC bot that subscribes to this channel and when it receives a message generates a paste of the traceback and pings me with a link to the traceback.
